The worst thing I have ever bought. Huge freezing and disappointing speed. No way to connect to a TV, it is impossible with the constant fluctuations in its speed. Stay away.

Quite fast with a large memory and convenient for your keys! It doesn't heat up as much as other flash drives!

It is a pretty good USB stick. (Tested on Thira 2.0) Writing speed 31mb from *HDD*. Very good and worth its money

Slow with unjustifiable fluctuations during the transfer of large files. Perhaps the worst I have tried on USB3. It barely reaches 15mb/s write speed for me, tested on 3 PCs. Don't be swayed by the price. I do not recommend it.

I bought the product a long time ago (about 3 years ago). I used it for about 1.5 years until it stopped working. They replaced the product with a brand new one which has been working fine for 1+ year now. (the store where I bought it provided a lifetime warranty for the product)
Its speeds are moderate but satisfactory for its price.
Also, I want to mention that it fell from the 1st floor and continued to function perfectly for a while, until I sent it back and they replaced it, as I mentioned. So, personally, I find it very durable, although I read different things in other reviews...
Overall, I recommend it, although it is relatively old as a model. However, it remains reliable for its price, although it may not satisfy a very demanding user.

Simply put:
Positives:
Quality construction
Lifetime warranty
Read speed of over 90mb/s on average.

Negatives:
Slow write speed, averaging below 10Mb/s.
Slow access time of 2ms (when all my other devices are below 0.5ms)

Three of them burned after 2 months of use each.

I was able to fix them with fdisk, but they only lasted a few uses before completely burning out.

Fixed recording speeds (~45 MB/s), lifetime warranty, and good build quality.
Excellent in its category!

Great capacity (16GB) for its price (6.5€).
Easy to use and secure its drawer.
BUT the recording at 40MB/s is not valid. The maximum I recorded is 13MB/s on a USB 3.0 port.

Good and quite fast for its price (22€) even on usb2.
On USB2:
Read: 32MB/s
Write: 20MB/s
Its actual capacity is 58GB.
